The Old Manse, historic house and 9 acres of field, orchard, and floodplain along the Concord RiverManagement area description:
3 acres of native grassland dominated by little bluestem and associated riverbank
Acres in the management area: 3 Listed on EDDMaps? Yes
Habitat type: Field/forest edge, Fields, Stream bank
Was this Early Detection Rapid Response (EDRR)? NoInitial Overall Invasive Distribution Description:
Invasives had colonized field and stream bank and were disbursing throughout habitat. Invasive ranged from 100% cover to scattered plants
Initial Overall Percent Cover of Invasives: 26 - 50%
Eradication from site
Approximate project start date: August 13, 2009
Years this project has been ongoing: 10Project summary:
All swallowwort was treated with herbicide
Control method: Chemical, Manual
Disposal method: Left on siteDetailed project timeline:
Swallowwort at TOM has been treated annually with Garlon 3A in mid to late summer (July or August). Where plants were abundant they were treated using 4% mix using a mist blower and a 2% mix in a backpack sprayer where they were scattered. Data from 8 monitoring plots is collected annually prior to herbicide treatment.
Final acres in management: 3
Open to the public: Yes
Able to Provide Tours: No
Success Rate: Moderately successful
Current Overall Percent Cover of Invasives: 0 - 5%Comments / Takeaways
Garlon does a great job on swallowwort, many years of treatment are necessary since small plants are easily overlooked and the seed bank appears to need to be exhausted.
Update: Although it took many years, we have achieved good control but we need to continually search for any seedlings that may get established.
